Effects of the Support-Crystal Size on the Catalytic Performance of RuO2/TiO2 in the Deacon Process

RuO2/TiO2 catalysts with different TiO2 crystal sizes were prepared via a dry impregnation method, and these prepared catalysts were applied in the oxidation of HCl. The results show that decreasing the support-crystal size is an effective method to enhance the dispersion of RuO2 on TiO2, which is helpful to increase the catalytic activity significantly.
